In this research, the high temperature Fine Particle Bombardment (FPB) treatment system was developed. This system is a combination of FPB treatment and high frequency induction-heating. The specimen was produced in temperature ranging from room temperature to 900℃. From element analysis, using SEM and EDX, series of processing temperature higher than 600℃ a layer containing Cr element of shot particle was observed. In addition, by structural analysis using XRD, it was revealed that this layer is FeCr_2O_4. Then, the corrosion resistance was evaluated for each series using electrochemical measurement in 3%NaCl solution. From these results, corrosion resistance improved as the treating temperature rose, and Cr-900 series, samples treated at 900℃, showed a good corrosion resistance.
